I've had epilepsy for 60 years. It will be stable for a while (whatever stable is at that time) then one day the frequency and intensity for no apparent reason changes. For me alot of triggers. As with all of us stress is the biggest one. According to a pharmacist I had, it can cause your meds to be less effective. Then of course many other triggers. My doctor started sending me for more in depth study because the seizures were happening every 3 weeks, over the course of 3 days, just having 2- 3 seizures a day. But now.... it suddenly appears to be calm. I thought to myself " finally. Thank goodness I'm finally going to get some help. Then it all but stopped. At least not frequent. Frustrated again.

I've had my activity change on and off over the years .
It's kinda like getting an unexpected flu, broken ankle or back out of place
sometimes I know the reasons and sometimes I haven't the faintest

I agree with you and your post and the other people's posts here, I think it's dif per person, I have mine are more stable than before but they come about at random sometimes and I have nocturnal ones and grand mal once in a while, so it fluctuates with the individual I think and we may have the same condition but we all are different than the other person, and hang in there and try and stay pos, my opinion here
